This invention relates to suction cleaners in general and particularly to means for removably securing a suction cleaner dust bag to the body or main casting of a suction cleaner.

Suction cleaners are generally provided with means for securing a dust bag directly to the discharge outlet of the suction cleaner. These conventional cleaners are made in various sizes and shapes and are provided with a particular typoof a bag which will only fit the cleaner for which it was specifically designed. None of these cleaners, however, are provided with detachable means whereby a different type of bag can be used.

The present invention provides means whereby all types of machines may be equipped with bags other than those origi nally intended and the primary object of the invention is to provide new and usefulmeans for detachably connecting a dust bag to suetion cleaners by providing certain kinds of disconnectible members to fit various types of cleaners so that bags of different kinds and sizes may be readily applied to existing connected to the suction cleanerbody, and

which is provided with means'for securing bag clamping means thereto.

Another object of the-invention is to provide an adapter member which may be detachably secured to the main body of a suction cleaner and which receives a bag clamping member of novel design which will detachably maintain the dust bag in proper position relative to the cleaner.

Another object of the invention is to provide new and useful bag securing means for quickly and easily applying a dust bag to or removing it from a suction cleaner.

Another object is to provide a bag clamping member which is detachably connected to a suction cleaner, and which is provided with novel means for quickly and easily releasing the bag and holding it in proper position relative to the clamping member.

Other objects and advantages will be apparent throughout the progress of the fol lowing specification.

The invention comprises in general an adapter member which is detachably connected to a suction cleaner, whereby the suction cleaner will be adaptable for use with types of bags otherthan those for which the cleaner was originally intended. Bag clamping means is detachably connected to the adapter member, and it is provided with 60 means for removably attaching a dust bag thereto. The detachable adapter member which carries the bag clamping means by which the bag is detachably connected permits bags of different types to be used on any type of cleaner, regardless of its size; shape or construction.

In the accompanying drawings illustrating a selected embodiment of the invention the views therein are as follows:

Referring tow the drawings, 10 designates generaly a suction cleaner body having the discharge outlet 11 formed thereon. A flange 12 is provided on the discharge neck 11 and receives the flange 13 which is formed on the adapter member 14. The flange 12 is thickened or enlarged at 15 and supports the screws 16, which extend rearwardly from the flange 12. The flange 13 may be provided with loops or ears 17 which will angage the screws 16, and thumb-nuts 18 threaded on the screws 16 hold the adapter member 14 in proper position on the discharge outlet neck 11.

Bag clamping means 19 is provided to receive and hold the bag and is adapted to be detachably connected with the adapter member 14, Fig. 4. The bag clamping means 19 has a collar 20 which fits telescopically over the reduced end 21 of the adapter 14, the collar 20 being provided with bayonet grooves 22 which engage with the lugs or pins 23 formed on the adapter 14 for positively locking the two members together. A rubber ring or washer 24 is arranged in the annular groove 25 in the bag clamping means 19 so that when the two parts are connected together the member 19 will bear tightly against the outer edge 26 of the adapter 14. Air and dust are thereby prevented from seeping through this connection. The outer portion 27 of the bag clamping means 19 is provided with an annular groove 28 in which a spring 29 or other yieldable member is arranged. This "yieldable member 29 may be conveniently formed of spring wire and is provided with a pair of loops or bends 30 which extend through opening 31 in the outer portion 27 of the member 19. This arrangement permits the spring 29 to expand within the groove28, and holds it from accidental displacement from its plane, also providing a little play during operation of the'spring member 29. A neck member 32 is provided within the member 19 and is tapered at 33 sothat the dust bag 34 may easily fit over the end thereof, being received in an annular recess between the members. The inner end of the neck 32 has a turned end or flange 35, which is secured to the inwardly extending portion of the member 27 by welding both to an interposed washer 35 or in any other suitable. manner to provide a bearing for the rubber ring or Washer 24.

A support 36 is secured to the outer por tion 27 of the bag clamping means 19 to provide a pair of ears 37 which receive a fixed hollow shaft 38. An. operating lever 39 having a hollow body portion is arranged about the shaft 38 and is provided with a pair of cam surfaces 40 and 41.

The spring member 29 is provided with outwardly turned ends 42 and 43 which extend through and are guided laterally by a slot 44 in the hollow shaft 38. The ends 42 and 43 of spring ring 29 are adapted for engagement with the cam surfaces 40 and 41 respectively. The spring member 29 is of the expansion type and normally bears against the outer walls of the groove 28. When the handle 45 of the operating lever 39 is moved to theposition shown in Fig. 3 the cams 40 and 41 operate on the ends 42 and 43 of the spring wire and cause these ends to move inwardly into the narrow opening 46 formed at the meeting ends'of the cam surfaces 40 and 41. When the ends 42 and 43 of'the wire are together the device will attain the position shown in Figs. 3, 5 and 6. When the handle is operated in a reverse direction the spring member 29 will expand because the distance between the points of the cams 4O and-41 which engage the end: 42 and 43 will increase. When the handle is in one position, it can therefore be readily seen that the wire is expanded and the dust bag 34 may be easily slipped over the neck member 32 and within the outer portion 27 of the member 19. After the bag is in proper position on neck 32 the operating lever 39 is operated to the position shown in Fig. 3 and causes the cams to contract the spring and tightly clamp the bag 011 the neck 32. The operation is as follows: The adapter member 14 is provided with means whereby it may be attached to the main body of a suction cleaner. This adapter may be supplied in various forms, sizes, and shapes so that it may be applicable to various types of cleaners now on the market. The outer or reduced end 21 of the adapter 14 may be made standard so that it can receive the standard bag clamping means 19, which is, in this instance, the specific bag clamping means shown. As the clamping means 19 is securely fastened to the member 14 by means of the bayonet groove 22 and the pins 23,.it

.can be readily seen that the clamping means 19, to which the bag 34 is secured, can be disconnected from the adapter 14, and the bag removed and replaced after the clamping means is disconnected from the adapter. It is much more convenient to detach the clam p- .ing means 19 from the adapter member 14 to replace or clean the bag, than it would be to remove the bag from the clamping means when the cleaner is on the floor. ing the bag the bag clamping means may be held in the hand and then the bag may be inserted on the neck 32. The lever 39 is then operated to secure the bag in the bag clamping means 19. The operatorthen merely connects the clamping means 19 to the adapter member 14.

It is preferable that the adapter member 14 remain permanently connected to the suction cleaner instead of removing it at various times, although it is made detachable in case it is required to be removed at any time for any purpose whatever.

The invention provides simple and'efficient means for detachably connecting and supporting a particular type of dust bag to various types and kinds of suction cleaners regardless of their shape or size. This arrangement permits the use of bags of a certain In attachdesign to be used on any type of cleaner whatever, the only arrangement required being the installation of the adapter member 14.

Changes may be made in the form, construction and arrangement of the parts with out departing from the spirit of the invention or sacrificing any of the advantages thereof, and the right is hereby reserved to make all such changes as fairly fall Within the scope of the following claims.
